Multi-Plane Precision Levels with Calibration Certificate

These levels come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. They are precision-machined and check the accuracy of both horizontal and vertical surfaces simultaneously with two highly sensitive vials set at 90° angles.
Levels with heat-resistant insulation are protected from heat transfer that may affect level sensitivity.
V-groove provides stability on curved surfaces.
